Suppose you need to write a java program which needs to extract some information out of a XML file. One way would be to use a sax parser, with the disadvantage that you need pretty mutch code for extracting the needed informations. Another way would be to use an xpath expression witch is evaluated by a xsl processor like xalan. Problem is, that all xsl processors I know are using DOM, which means extensive memory usage.
Thatís what Xenon is all about, an implementation of Xpath and XMLQuery which uses a sax parser and which is especially optimized towards a small memory footprint.
The current release is a pre alpha release so you will not be able to use this for any good. But please feel free to take a look at the source code and tell me what you think.
To use it, put xerxes.jar ( get Xerxes from Apache
) and xenon.jar into the classpath. Then you can run it through:
java org.xenon.main.RunQuery QueryFileName OutputFileName
See the example directory for example Query Files.
Xenon is hosted by
